Lecture: Evacuated Tube System Concept Overview Blood in a patient's veins is considered 'whole blood.' It is a composition of ________ (liquid portion, 90% water), and the rest is formed elements including red blood cells (erythrocytes, RBCs), white blood cells (leukocytes, WBCs), platelets (thrombocytes), and other formed elements such as proteins, carbohydrates, lipids, minerals, more.).

There are 13, most made by the liver, that flow freely through our plasma at all times. They are chiefly responsible for the response involved with achieving hemostasis, the halting of blood loss. When blood leaves the body, whether by venipuncture, injury, or other means-- in a healthily functional body, the coagulation cascade is called upon immediately, and snaps into action. This calls upon these ________ to be drawn to the injured site, bind with thrombocytes and erythrocytes, and create a clot.

Plasma This is the liquid portion of blood which contains all clotting factors, as it would in the body. Serum This is the liquid portion of blood which NO LONGER contains clotting factors, as it has been allowed to clot, and the clotting proteins are contained in the clot of RBCs, platelets and other formed elements below. The remaining liquid is serum, no longer plasma, due to this ________.

Whole blood, kept close to how it naturally flows in our systems, is also used often. This is all blood components together-- plasma, with clotting proteins floating freely, along with RBCs, WBCs, platelets, other formed elements. Once blood is collected, if correctly inverted and collection handling and processing requirements are followed (lecture next week on using laboratory directory to find these requirements), then blood will settle and eventually yield one of these three ______. All laboratory tests will have required blood components as the necessary transport element for what the test is qualitatively or quantitatively testing for. Because of this, all blood collection tubes contain additives which either encourage the coagulation process (clot activators), or prevent it from occurring (anticoagulants), in order to meet a specific tests' requirements. Additive Types Clot Activators Enable blood to clot, yields ______. Anticoagulants Prevents blood from clotting, yields ______ or ______, depending on the additive type. No additive Empty. Contains no additive, blood will enter tube and clot naturally without properties altered. Will yield ______.
